JFCW

The JFCW series of single and dual output DC/DC converters provide up to 15 watts of output power in an industry standard package and footprint. These units are specifically designed to meet power needs in a low profile package. All models feature a 4:1 wide input voltage range of 9-36VDC or 18-75VDC. Some features include positive or negative remote on/off, 1600VDC I/O isolation, and trimmable output voltage. All models are also protected against over current, over voltage, input under voltage, and short circuit conditions.

1. MTBF: BELLCORE TR-NWT-000332. Case 1: 50% Stress, Temperature at 40°C. MIL-HDBK-217F Notice2 @Ta=25°C, Full load (Ground fixed and controlled environment).
2. Trimming allows the user to increase or decrease the output voltage set point of the module. This is accomplished by connecting an external resistor between the TRIM pin and either the +Vout pin or the -Vout pin.
3. The ON/OFF control pin voltage is referenced to -Vin. (See the "Product Standard Table" below for suffix options).
4. Heat Sink is optional. Consult factory for ordering details.
5. The JFCW Series can meet EN55022 Class A with external capacitors connected in parallel to the input pins. Recommended: 24Vin: 6.8uF/50V * 2 pcs; 48Vin: 2.2uF/100V * 2 pcs.
6. An external filter capacitor is required if the module has to meet EN61000-4-5. The filter capacitor Wall Industries suggests: Nippon chemi-con KY Series, 220µF/100V, ESR 48MΩ.
Due to advances in technology, specifications are subject to change without notice.
